[GRASS-user] NVIZ use in wxpython GRASS6.4

Good evening everyone

Maybe this sound like a (another!) newbie question but when I try to visualize data in 3D, in wxpython Map Display, I get a window saying:

  • Unable to switch to 3D display mode
  • The NVIZ python extension was not found or loaded properly.
  • Switching back to 2d display mode.
    Details: No module named grass6_wxnviz

But at File/NVIZ (requires tcl/tk) a menu is opened requesting elevation, raster colors, points and vectors and when I run the following is displayed in output command window:

nviz elevation=elevation_shade@PERMANENT,elevation@PERMANENT
(Wed Dec 02 15:04:49 2009) Command terminated (0 sec)

But nothing happened…

Question: Since it says that it requires tcl/tk shouldn’t it open a tcl/tk window? Or am I wrong?

Thank you very much in advance
Best regards,
